First sort the number form least to greatest
24,26,27,28,30,30,33,36
To find the mean, we divide to sum of all numbers in the data set by the number of numbers given,'8'.
(24+26+27+28+30+30+33+36)/8=234/8=29.25
Mean=29.25
To find the inter quartile range, we must solve for the lower and upper quartile mean.
Lower Quartile=(24+26+27+28)/4=26.25
Upper Quartile=(30+30+33+36)/4=32.25
32.25=26.25=6
Interquartile range=6
The median is the middle number in the data set, or the sum of the two middle numbers if there isn't a sole middle number
24,26,27,28,30,30,33,36
Median=(28+30)/2=29
Median=29
1st quartile we already solved for...
Lower/1st Quartile=(24+26+27+28)/4=26.25
3rd quartile we already solved for....
Upper/3rd Quartile=(30+30+33+36)/4=32.25
The mean would be most effected by an outlier of 52, the median would only go from 29 to 30.
